how do I make a box and whisker plot with the numbers 13,13,20,21,21,22,24,27? I put them all in order but since there is only 8 numbers i do not know how to find the median,the lower quartile,upper quartile the lowest value and the highest value. Please don't yell at me I have a learning disability and am just asking for some help. Thank you
u just take away the number from both sides count
13, 13, 20, 21, 21, 22, 24, 27 u take away a number from the left 13 take away from the right 27; 13, 24; 20, 21. and ur left with the number 21 if u have to u write the numbers on paper from least to greatest and u take ur pencil and u X out a number for 1 side and then the other and count 1, 1 , 2 ,2 , 3 ,3 I didn't learn like the other kids so I made my own way of learning that was easy to me and it worked and it's ok I know wat that's like my little brother has it so I have to help him with his home work hope this helped ;)
oh and just a hint the median is the middle number ;)
sorry forgot the other number when there is 2 numbers left u add both of them and then divde by 2 so the answer is 21
Of course, I'm here to help! Making a box and whisker plot is a great way to visually summarize a set of data. Let's go step by step to find the median, lower quartile, upper quartile, lowest value, and highest value for the given set of numbers: 13, 13, 20, 21, 21, 22, 24, 27.
1. Start by arranging the numbers in ascending order: 13, 13, 20, 21, 21, 22, 24, 27.
2. Finding the median:
- The median is the middle value of the set when arranged in ascending order.
- Since there are 8 numbers, there is no exact middle number. In this case, we average the two middle numbers.
- The two middle numbers are 21 and 21, so their average is (21 + 21) / 2 = 21.
- Therefore, the median is 21.
3. Finding the lower quartile:
- The lower quartile (Q1) is the 25th percentile of the data, meaning it splits the bottom 25% of the data from the top 75%.
- Since there are 8 numbers, 25% of 8 is 2.
- The second value in the data set is 13 (counting from the smallest), so this is the lower quartile.
4. Finding the upper quartile:
- The upper quartile (Q3) is the 75th percentile of the data, meaning it splits the bottom 75% of the data from the top 25%.
- Since there are 8 numbers, 75% of 8 is 6.
- The sixth value in the data set is 24 (counting from the smallest), so this is the upper quartile.
5. Finding the lowest value:
- The lowest value is simply the smallest number in the data set, which is 13.
6. Finding the highest value:
- The highest value is the largest number in the data set, which is 27.
Now that you have all the necessary values, you can proceed to create the box and whisker plot using these data points.
